I don't know about "best". I have a Jabsco reversing fuel pump on my boat for fuel transfer. I had to replace the impeller this last year. It doesn't get much use but the impeller was 7 years old. The pump moves fuel when I ask it to and other than replacing the impeller (which was cheap and easy) I've never had any issues.
BTW, I connected the pump to a relay with a timer on it. I found that if I didn't do that, I would forget I had turned the pump on with unfortunate results. The pump is really quiet which is a good thing other than I would forget.
